Patented May 2, 1933 UNITED STATES PATENT OFFICE 'lIL'IABLE FOUNTAIN BOTTLE Application filed March 12, 1931, Serial No. 522,026, and in Germany March 12, 1930 This invention relates to a bottle, the mouth of which is arranged near the bottom, so that the bottle has to be laid fiat when it is to be filled, the liquid in the bottle being maintained by vacuum in the bottle, when the bottle is in the upright position, so that liquid can .be withdrawn only underneath the liquid level, the bottle mouth remaining open. Such bottles are generally used as inkstands with the view to ensuring an economical consumption of ink.

This invention relates especially to a new and advantageous construction of the bottle mouth, designed to ensure an easy filling and a complete emptying of the bottle, as well for thinly liquid substance as for viscous substances, such as ink, glue, benzine, acids, medicaments and the like. With this object in View, a concave collecting space and air channels are arranged in the'funnelshaped bottle mouth, whereby clogging or overflowing at the filling or emptying oi the bottle are prevented. The mouth may further be sunk completely in the wall of the bottle or formed by this wall, a closable opening being arranged in the same, so that the closing element is also sunk in the side wall of the bottle.

Several embodiments are illustracd by way of example in the accon1pan \'ing draw- 111g in which Fig. 1 shows in vertical section a bottle in the position for use, designed to serve as inkstand.

Fig. 2 shows this bottle in the turned over position for filling.

Figs. 3, 5 and 7 show each a modified construction of the filler in longitudinal section.

Fig. l is a cross section on line IV-IV of Fig. 3.

Fig. 6 is a cross section on line VIVI of Fig. 5. I

Figs. 8,9, 10 and 11 show each a different form of construction of the'filler in longitudinal section.

In all figures of the drawing a designates ;a glass bottle of any suitable form designed to hold ink, glue, acids and the like. In the form of construction shown in Figs. 1 and 2 the bottle a has a portion 1) of its wall cut out a short distance above the bottom. In this out out portion b a tunnel or filler 0 is inserted which has in its upper portion on the outer side a deep semispherical cavity (2 forming an enlargement of the mouth of the filler and merging into a tubular neck portion 0." The on vcd portion d of the filler is sunk in the bottle so that its convex side is turned towards the interior of the bottle, whereas the tubular neck portion 0 extends into the bottle at an acute angle, reaching to close above the bottom. The outer mouth of the filler is oval and adapted to be closed by a lid 0. On the lid 0 a clamping springf may be fixed, designed to hold blotting paper or the like. The inner half 9 of the lower edge of the neck portion 0 of the filler is bent so that it extends parallel to'the bottom of the bottle. When the bottle has to be filled, it has to be laid flat as shown in Fig. 2.- The liquid is then poured into the cavity (Z of the filler and flows from this cavity into the tubular neck portion 0 and over the bent over edge portion 9 into the bottle. The cavity (l prevents the tubular neck portion 0 being completely filled with liquid, when the air displaced from the bottle could not escape. so that overflowing or spilling of the v liquid would occur. The curved edge portion 9 of the filler guides the liquid flow into a vertical direction, so that the air from the bottle can flow out without being impeded. After the filling the bottle. a. is brought into the upright position as shown in Fig. 1. The liquid rises in the filler only so high, that the inner mouth of the filler is filled and the liquid can be easily withdrawn by means of a pen, brush, or similar instrument. To empty the bottle, it is accordingly inclined towards the filling open in the bottle as described and shown in Fig. 2 the filling and the emptying is'comparatively simple with the aid of the cavity 02 and owing to the large cross section of the filler neck 0. This large cross section the liquid. In inkstands it is desirable, that therefore advisble to make the filler narrower near the inner end. Hcrefrom result however difliculties at the filling of the vessel, as the narrow filler mouth is easily filled by the liquid so that the air displaced from the bottle cannot well escape. This danger is avoided by the arrangement of air channels, according to the invention.

In the form of construction shown in Figs.-

3 and 4., the filler neck 0 is nar1'owed towards the inner side, so that it is impossible to completely insert a pin through the same. The cavity d serves for pouring in the liquid as described with reference to Figs. 1 and 2. The liquid, flowing over at the filling of the vessel from the cavity (Z into the neck portion '0 of the filler, might clog the narrow neck portion 0. In that part of the wall of the neck 0, which is on top when the vessel is laid flat, that is in the filling position, an air hole i is arranged close to the inner surface of the bottle wall so that air from the bottle can escape, even if-the narrow inner mouth of the filler neck is completely filled with liquid, flowing over the liquid at the filling being thereby prevented; The fillcr neck terminates in the bottle a ce'rtaii. distance from the bottle wall. \Vhen emptying the bottle by inclining the same towards the filler side, the liquid behind the bottle neck can flow out through this hole 2'. When the bottle is in uprightposition, the liquid rises to the lower edge of the filler and at the side of the same up. to the air hole 2'. The inner wall 2" of the hole 2' is curved towards the inner wall of the filler neck so that the liquid can flow over. into the filler neck and fill the same up to the height of the edge of this hole.

In the form of construction shown in Figs. 5 and 6 the filler ends in the bottle directly on the bottle wall, as shown in Fig. 1, hav

ing however amarrow neck portion 3, as shown'in Fig. 3. The air displaced from the bottle at the filling can escape through the channel Z, which joins the outer side of the filleruieck. When the bottle is in use, this channel Zmaybe closed by a-stopper k. The liquid rises in the filler neck until the inner mouth of the same is closed, the

' fair channel Z beingclosed or shut ofi' at the same time.

The form of construction shown in Fig. 7 corresponds substantially to-gthe form of construction shown in Fig. a tubular socket j beinghowever provided onthe bot tle ,neck instead of an air hole. This tu bular socket j prevents the liquid from rising on the inner surface of the bottle neck up to theouter mouth of the air hole, the liquid rising only until the lower mouth of this tubular socket has been shut off by the liquid. The inner, wall of the tubular socket 7' may be curved at its upper edge towards the interior of the filler neck as indicated by j, in order that also the lower portion of the bottle can fill with'liquid. If this air channel y or the air hole '11 in Fig. 3 were not rounded as shown and described or, ifthe liquid is too thick to flow over through the air hole into the filler neck, no liquid will fill this filler neck as shown in Fig. 8. In order to obtain a medium height position of the liquid level between the mouth of the air hole 2' or the air channel and the lower mouth of the filler neck, a second air hole It is provided in the filler neck, and the tubular socket j is extended in downward direction, so that its lower mouth is closed when the liquid has risen in the filler neck up to the air hole h and closes the same as shown in Fig. 9. The vessel 0, shown in Fig 7 has further an inwardly curved portion a of the bottle wall at the upper end of the cut out portion so that the filler can be completely sunk into the bottle.

In the forms of construction shown in Figs. 8 to 11 the cavity (Z' is formed by the bottle wall, wherefrom results a simpler construction of the filler, which can then be fitted with seating faces m for a dabbing instrument n of glass (Fig. 8), or for a brush 0 (Fig. 9), or for a closing stopper 7) (Fig. 11). The closing stopper is situated on the inner side of the bottle wall. In this form of construction a simple tube 2? can be used as filler neck, which is inserted into a hole 1' formed by the cavity 05' of the bottle wall, the wall of this cavity being partly cut open, as shown in Fig. 10. This tube t may be closed by a stopper .9. The bottle or vessel of this form of construction 1s especially designed to hold acid. For emptying, the vessel has to be simply lnclined more or less. For complete emptying a syphon catch andconduct the liquid poured therein through the aperture into the bottle, and means for allowing the escapement of an from the bottle through the aperture when it is being filled.

2. In a tiltable fountain bottle having a removal aperture in one vertical Wall adapted to serve for filling the bottle when the bottle is resting on opposite vertical wall and a cavity near andcommunicating with this aperture, a funnel shaped neck extending from the cavity to near the bottom of the bottle communicating with the aperture adapted to guide the liquid pouredinto the cavity to the bottom of the bottle, and means for allowing the eseapement of air from the bottle through the neck and the aperture when liquid is being poured into the cavity. 3. In a tiltable fountain bottle having a removal aperture in one vertical wall adapted to serve for filling the bottle when the bottle is resting on opposite vertical wall and a cavity near and communicating with this aperture, a funnel shaped neck extending from the cavity to near the bottom of the bottle communicating with the aperture adapted to guide the liquid poured into the cavity to the bottom of the bottle, and a channel at the side of and parallel to the neck leading through the side wall of the bottle adapted to allow the escapement of air from the bottle when it is being filled.

4. In a tiltable fountain bottle having a 2 removable aperture in one vertical wall adapted to serve for filling the bottle when the bottle is resting on opposite vertical wall and a cavity near and communicating with this aperture, a funnel shaped neck ex- 2 tending from the cavity to near the bottom of the bottle communicating with the aperture adapted to guide the liquid poured into the cavity to the bottom of the bottle, and a channel in the wall of the neck extending parallel to the vertical wall of the bottle provided with the aperture and close to the inner surface of this wall adapted to allow the escapement of air from the interior of the bottle when it is being tilted. In testimony whereof I affix my signature.
